CUTTING AND FOLDING MACHINE.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Cuttingand Folding Machines, of which the following is a specification.

In sheet cutting and folding machinery where the'sheets are slitted after they have been folded a plurality of times, it has been found diflicult to accurately slit the; so folded sheets because of their extreme thick- A practical embodiment of my invention is represented in the accompanymgdraw ings, in which- Figure 1 is a diagrammatic vertical section taken from front to rear through so much of a sheet cutting and folding machine as will give a clear understanding of my invention,

Fig. 2 is a vertical section taken through the machine from front to rear just inside the near side frame,

Fig. 3 is a similar view taken just inside the far side frame,

Fig. 4 is a view of the gearing connecting the several parts,

Fig. 5 is a detail top plan view of one of the sheet delivery devices, and

Fig. 6 is a detail view showing the means for moving the gripper controlling cam when the first folding blade cylinder is used as a collecting cylinder.

In the embodiment of the invention shown herein, a plurality of narrow webs are fed through the rolls 1, 2, to the rotary cutters 3, 4, where the webs are cut transversely into sheets which are fed through guides 5, 6, between the folding blade cylinder 7 and the folding jaw cylinder 8. The folding blade cylinder 7 is mounted on a shaft 9 and carries a set of grippers 10 and a folding blade 11. The'folding jaw cylinder 8 is mounted on a shaft 12 and is provided with two sets of folding jaws 13, 14, arranged to successively coact with the folding blade 11. '1

The once folded sheets are transferred from the folding jaw cylinder 8 to the slit Specification of Letters Patent.

ting cylinder 15 mounted on the shaft 16, which slitting cylinder is provided with two sets of grippers 17, 18, arranged to receive the folded sheets from the folding jaws 13, 14, respectively.

A slitting device, including one or more slitting disks 19, carried by a cross bar 20, is arranged to coact with the cylinder 15 to slit'the once folded sheets longitudinally of their travel into a plurality of sections. The once folded and slitted sheets are then transferred to the folding blade cylinder 21, which cylinder is provided with two sets of grippers 22, 23, arranged to receive the folded and slitted sheets from the grippers 17, 18, respectively, of the slitting cylinder 15. This folding blade cylinder 21 is mount ed on a" shaft 24 and carries two folding I blades 25, 26, arranged to coact'respectively with the folding jaws 27 on the cylinder 28 and the folding jaws 29 on the cylinder 30.

These two folding j aw cylinders are mountsition to receive the slitted and folded sheets.

from the folding jaw cylinders 28, 30, respectively.

The folding mechanisms herein shown are of the well known floating folding blade and jaw type, the cam for controlling the floating of the blade 11 being denoted by 35 and the cam for controlling the floating of the blades 25, 26, being denoted by 36.

The cam for controlling the floating of the folding jaws 13, 14, is denoted by 37 the cam for controlling the floating of the folding jaws'27 is denoted by 38, and the cam for controlling the floating of the folding jaws 29 is denoted by 39.

The grippers 10 of the first folding blade cylinder 7 are opened to receive the advance edges of the sheets by a cam 40 and are opened to permit the folding off of the sheets by a cam 41.

The jaws 13, 14, of the first folding jaw cylinder 8 are opened by a cam 42 to permit the folding on of the sheets from the cylinder 7 and the said jaws are opened to permit the transfer of the once folded sheets to the slitting cylinder 15 by a cam 43.

Cams 44, 45, control the opening ofthe grippers 17 18, for receiving the sheets from the cylinder 8 and releasing them to the second folding blade cylinder 21.

A cam 46 is arranged in position to open the grippers 22, 23, to receive the sheets from the cylinder 15, cam 47 is provided for opening the grippers 22 to permit the folding off of one group of folded and slitted sheets to the cylinder 28, and another cam 48 is provided for opening the grip pers 23 to permit the folding off of the next succeeding group of folded and slitted sheets to the cylinder 30. p

A cam 49 is provided for opening the folding jaws 27 to p'ermitthe folding on of a folded and slitted group of sheets and a cam 50' is provided for opening said jaw 27 to deliver the sheets to the delivery device 33. i g

A cam 51 is provided for opening the 29 to permit the folding on of the succeeding folded and slitted group of sheets and a cam 52 is provided for opening the jaws to permit the delivery of the sheets to the delivery device 34.

A train of gears 53, 54, 55, 56, 57, 58, con"- nect the cylinders 7, 8, 15, 21, 28 and 30. p

The rotary cutters3 and 4 are driven from the gear 54 through the gears 59, 60, 61 and 62.

A series of pressure rollers 63 on the shaft 64 hold the sheets in register on the slitting cylinder 15 when the grippers 17, 18, are open for transferring the sheets to the cylinder 21. p t

A series of pressure rollers 65 on the shaft 66 coact with the cylinder 28 and a series of pressure rollers 67 on the shaft 68 coact with the cylinder 30 for controlling the delivery of the sheets. i I

Instead of folding off each group of sheets as they are cut from the webs; the folding blade cylinder 7 may be used to collect the groups 6f sheets. In this instance, one of the folding jaws 13, 14, is rendered inoperative and the cam 41 may be made movable and controlled by a cam 69 on the shaft 12 to operate the grippers 10 every second revolution of the cylinder 7 instead of every revolution thereof.

In this case a series of pressure rollers 70 carried by the shaft .71 coacts with the cylinder 7 to hold the first group of sheets in register while the grippers are opened fer receiving the advance edges of the second group of sheets.

By the term cylinder as used in the description, I contemplate any suitable means for passing the sheets and. signatures through the prescribed path and by the term grippers? I wish to include any engaging devices suitable for the purpose of leading the sheets or signatures through said prescribed path.

While I have shown associated webs passing between the rollers 1, 2, it is .to be understood that a single web might be passed between these rollers and handled in the manner set forth for the associated webs, without departing from the spirit and scope of my invention.-
